DOOR-STAY.

Specification of Letters Patent.

Patented Dec. 36,1913.

A pplicationfiled September 23, 1912. Serial No. 721,800.

To all whom it may concern:

Be it known that I, OSCAR C. RIXsoN, a citizen of the United States, and a resident .of New Rochelle, county of Westchester,

State of New York, have invented a new and useful Improvement in Door-Stays, which is I fully set forth in the following specification.

My invention relates to means for preventing a door from openlng beyond a predetermined extent, say n nety degrees; and

consists of a novel device for. accomplishingthat purpose, which is simple to construct and assemble, reliable in service, durable, compact, not obtruding into the door-way when the door is opened, and automatically retracting itself into its compact position when the door is closed.

Broadly speaking, my invention comprises a resilient member arranged in loops normally lying close together, and preferably with a vertical axis, andconnected at one end to the door and at the other end to the frame of the door-way or other stationary support, so that the loops are distended by the opening of the door, while upon the closing of the door the loops will automatically rearrange themselves in their normal compact form.

The invention consists further of the particular manner of constructing, arranging, and connecting the resilient member of my novel door-stay; and in the various details hereinafter pointed out and claimed.

The invention will be best understood in connection with the accompanying drawings, which illustrate a preferred embodiment thereof.

In these drawings, Figure 1 is a vertical section through the upper part of a doorcasing and door (in closed position), equipped with one form of my novel doorstay; Fig. 2 is a horizontal section through the door-casing, showing the door in plan, illustrating the door as in open position, and held by my door-stay against further swing; Figs. 3 and 4 are a plan and a longitudinal section respectively of a detail.

lis the door, hinged at 2 to the facing or door-jamb 3; and 4' is the head-casing or lintel of the door-way.

5 is a bracket-plate having the vertical depending stud or pivot 6, and secured to the lintel 4, as by screws.

7 represents a coupling-eye fast upon the end of the resilient member 8, and pivoted upon the stud 6. At the other end of the resilient member 8 is a similar couplingeye 9, pivoted between the ears of a bracket 10 .Which is secured to the face of the door 1,

as by screws.

Figs. 3 and 1 illustrate a preferred construction of the coupling-eye, which consists of a block or casting 7 cored to provide a longitudinal channel 11 (Fig. 1) communicating with an annular cavity 12 (Fig. 3), the annular channel being defined by a centrally-located cylindrical web 15 which surrounds a transverse hole 141. This end of the casting is then split, as at 15 (Fig. 4). One end of the resilient member 8 is inserted through the channel 11 and bent around to occupy the annular chamber 12; after which the two jaws (produced by the split, 15) are forced together, to clamp the end of the member 8 and hold it firmly in place. The other end of the resilient member 8 is similarly secured to a similar coupling-eye.

The resilient member 8 is preferably arranged in a series of convolutions or loops constituting a helix having a substantially vertical axis, and is of sufficient resilience to hold its loops normally in the more or less close relation indicated in Fig. 1. One coupling-eye is mounted upon the vertical pivot 6 depending from the lintel 1; and the other coupling-eye is likewise connected to the vertical pivot carried by the bracket 10 upon the door itself. Preferably the member 8 is made up of the core 16 of twisted or coiled steel wires and the coiled-strip sheathing of brass or the like (as indicated in Fig. 3), though either might be employed to the exclusion of the other. And whichever form of member is employed, it is so tempered as normally to lie in the compara tively close helical convolutions or loops shown in Fig. 1. The primary convolutions of the resilient member (whether the steel wires 16 or the brass sheathing-strips, both as seen in Fig. 3) are designated coils, and there will be practically no variation of the compactness of these coils; whereas the larger convolutions into which the resilient member forms itself will be referred to for distinction as loops.

When the door is opened, the loops of the resilient member 8 are distended, as indicated in Fig. 2; and when the door is closed, the resilience of the member 8 will restore its loops to the compact arrangement shown in Fig. 1. It is not essential to my door-stay silience to serve as a door-closer; it is suiticient for the present purpose that there be resilience enough merely to take up the slack which would otherwise be caused in closing the door.

I have described my invention with considerable particularity, but only for the sake of clearness; since my invention is not limited to the precise construction and arrangement set forth, but may be embodied in various forms. 7

Having thus described my invention, I claim:

1. The combination with a door and its casing, of a stud protruding at right angles from the casing, a coupling-eye pivoted thereon, a pivot carried by the door parallel to the face thereof, a coupling-eye mounted thereon, and a coiled and looped resilient member secured rigidly at its ends to said coupling-eyes and constituting a door-stay, said member being normally disposed in more or less compact loops when the door is closed, and said loops being distended when the door is opened.

2. The combination with a door and its casing, of a stud depending vertically from the head-casing, a coupling-eye pivoted thereon, and a coiled and looped resilient member secured at one end to said couplingeye and at its other end to said door, said member constituting a door-stay and being normally disposed in compact loops having a vertical axis when the door is closed but being distended by the swinging open of the door.

3. A door-stay comprising a pivot depending vertically from the lintel, a vertical pivot carried by the door, a coiled resilient member disposedin loops and with its ends connected to said pivots.

at. A door-stay comprising a coiled member arranged in compact loops and connected to the door and to a stationary support in such manner that the opening of the door distends said loops, said member having sufficient resilience to resume its compact arrangement upon closing the door.

5. A door-stay comprising acoiled and looped resilient member secured to the door and to a stationary support respectively, said loops being distended by opening the door, and automatically drawing themselves together when the door is closed.

6. A door-stay comprising a looped resilient member secured at its ends to the door and to a stationary support respectively and being of such length as to permit the door to open to a predetermined distance and no farther, the loops of said member being distended by the opening of the door and automatically looping themselves up when the door is closed.

7. A door-stay adapted to be secured permanently tothe door and to the door-casing respectively to limit the opening of the door, the same consisting of a looped member of such resiliency as to take up its slack automatically when the door isclosed.

8. A door-stay consisting of a coiled resilient member secured at its ends to the door and to a stationary support respectively, of a length to limit the extent of the outward swing of the door, said member automatically looping itself up beneath the lintel upon the closing of the door.

9. A door-stay consisting of a self-looping member connected to the door and to a stationary support respectively, of such length as to limit the outward swing of the door,

the loops there-of being distended by the opening of the door and automatically looping themselves up upon the closing of the door.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
